Rotala rotundifolia is highly adaptable and can grow in a variety of aquarium conditions. Under moderate light, its leaves remain primarily green, but higher light and CO2 injection encourage its characteristic reddish hues, especially on the upper portions of the plant. Regular trimming is necessary to maintain a bushy, compact appearance and prevent it from becoming leggy. It absorbs nutrients from both the substrate and the water column, so liquid fertilizers and root tabs help ensure healthy growth.

This plant is ideal for midground to background placement in aquascapes and works well with other textured plants to create contrast and depth. Its dense growth also provides hiding spots for small fish and shrimp, enhancing the natural feel of an aquarium.

Interesting Fact: Rotala rotundifolia is known for its rapid adaptation to different environments. Its leaves will change shape and color depending on whether it is grown submerged or emersed, a feature that reflects its natural versatility in transitioning between flooded and dry conditions in the wild.
